How the Land and Mortgage Register Is Structured and How to Read It Before Buying an Apartment or House in Poland

Understanding the structure of the land and mortgage register (Księga wieczysta, KW) is one of the foundations of a safe property purchase in Poland. If a buyer knows where to check the owner, where to look for restrictions, where to verify the mortgage, and what to pay attention to beyond the main sections, they act consciously rather than blindly.

For many buyers, KW initially looks like a complicated legal document. In practice, however, its structure is very logical. If you understand how the register is built and in what order to read it, you can identify a significant share of the risks in advance and avoid mistakes before signing the agreement.

If you first want to understand why KW is considered the key document protecting the buyer, start with the main guide:

Why the Structure of KW Is So Important for the Buyer

The land and mortgage register is built according to a clear logic. It helps you understand step by step:

• what kind of property this is
• who has the legal right to dispose of it
• whether other people have rights to it
• whether the property is encumbered by a mortgage
• whether there are legal restrictions that may affect the transaction

That is why KW should be read section by section, not as one continuous text. Many buyers make the mistake of checking only the owner’s name and whether there is a mortgage, while skipping everything else. In practice, risks are often hidden in the details.

Section I-O – Property Designation

This section contains the basic data about the property:

• address
• area
• plot number
• description of the premises or land
• identifying data of the property

This is the first technical filter for the buyer. Here you need to check that the property listed in the register really matches the one you saw in the listing, in the documents, and on site.

If you are buying an apartment, pay attention above all to the address, size, and description of the premises. If you are buying a house or a plot, check especially carefully the plot number, land description, and whether the property matches its actual condition.

At this stage, the buyer should answer the first basic question:
is this definitely the property I am planning to buy?

Section I-Sp – Rights Related to Ownership

This section is especially important when buying houses, terraced units, townhouses, and plots.

It may include rights connected with the property, such as:

• right of way for vehicles
• right of passage on foot
• rights related to access to a road
• other rights without which using the property would be difficult or impossible

For an apartment, Section I-Sp often looks uneventful. But for a house outside the city or a plot, it may be critical. This is where it may be shown whether the property has legally regulated access to a road.

If the buyer ignores this section, they risk ending up in a situation where the house has been formally purchased, but issues of access, passage, or use of related infrastructure remain problematic.

Section II – Ownership

This is one of the key sections for the buyer. It shows:

• who the owner is
• whether there are co-owners
• sometimes another entitled entity

The main question here is very simple:
does the seller match the person listed in the register?

If not, it is necessary to clarify immediately on what basis the seller is involved in the transaction. Different situations are possible:

• the seller acts under a power of attorney
• the property is in the course of inheritance proceedings
• there are several owners
• a spouse’s participation or consent is required
• the seller does not have full authority to dispose of the property

If the buyer sees one seller in the listing but a different ownership structure in KW, this does not always mean a problem, but it always means that additional verification is necessary.

Section III – Rights, Claims, and Restrictions

This is the most sensitive section of the register from the point of view of risk assessment.

This is where entries may appear concerning:

• easements
• personal easement of residence
• right of lifelong maintenance or residence
• claims
• warnings
• bailiff enforcement proceedings
• restrictions on disposing of the property
• third-party rights that may affect the use of the property

This section answers one of the most important questions for the buyer:
do other people have rights, claims, or restrictions that may prevent peaceful ownership of the property after purchase?

For a detailed explanation of which entries in Section III and in other parts of the register should genuinely alarm a buyer, read the separate guide:
Dangerous Entries in the Land and Mortgage Register: What Should Alert a Buyer

Section IV – Mortgage

This section states:

• whether there is a mortgage
• who the creditor is
• what the secured amount is
• what type of mortgage it is

For the buyer, it is important to understand that a mortgage in itself does not make the transaction impossible. Many properties in Poland are sold with an active mortgage. However, the buyer must clearly understand how exactly it will be repaid, what documents will be provided, and how the KW entry should change after the transaction.

If the seller cannot clearly explain the mechanism for closing the mortgage, that is already a risk. The buyer should not only see that a mortgage exists, but understand what will happen to it in practice after the agreement is signed and the settlement is made.

What Else Matters Besides the Main Sections

Many buyers read only Sections I–IV and overlook wzmianka — a note that an application, complaint, appeal, or other procedural action has been filed.

This is a serious mistake.

Wzmianka may mean that:

• a procedure concerning the register has already begun
• the content of the register will soon change
• the current picture may be temporary
• new entries may appear in KW in the near future

For the buyer, this is always a signal to stop and find out what exactly has been filed, on what basis, and how it may affect the transaction.

How to Read KW Step by Step

In practice, the most convenient approach is to follow this sequence.

First, check the property description in Section I-O.
Then review the rights related to ownership in Section I-Sp.
Next, verify the owner in Section II.
After that, review restrictions and risks in Section III.
And only then move to the mortgage in Section IV.

This order helps you avoid missing important details and getting lost in the information.

It is very important not to ask yourself only the question:
“What is written here?”

You also need to ask the second question:
“What does this mean for me as the future owner?”

What Questions Should You Ask Yourself While Reading the Register

When reading KW, it is useful to check the following for yourself:

• is this definitely the property I am buying
• does this person really have the right to sell it
• will another person need to participate in the transaction
• do third parties have rights of residence, passage, vehicle access, or use
• is there any dispute that may change the legal status of the property
• could the mortgage become my problem after the transaction
• is there a wzmianka showing that the register may soon change

This is exactly what distinguishes a formal reading of the document from a real property check before purchase.

When It Is Better to Ask for Help

Reading KW on your own is useful, but it is not always sufficient. It is better to involve professional help if:

• the property has several owners
• the property was acquired through inheritance
• there are entries relating to claims or restrictions
• there are unclear formulations in Section III
• there is a wzmianka
• you are buying a house, plot, or townhouse
• the mortgage is to be repaid during the transaction
• the buyer still has doubts after reading the register

It is also important to understand the limits of the notary’s role — this helps avoid shifting onto the notary the part of the verification that the buyer should consciously go through themselves. Read more in the guide:

Why This Issue Is Especially Important for Houses, Plots, and Townhouses

When buying an apartment, checking KW is very important. But when buying a house, plot, or townhouse, it becomes even more important because there are usually more risks involved.

In such cases, you need to pay particularly close attention to:

• rights related to access to a road
• the description of the land and plot
• easements
• usage rights
• land-related restrictions
• the ownership structure and related entries

That is why, for properties connected with land, a superficial reading of KW is almost never enough.

Conclusion

At first glance, the structure of the land and mortgage register may seem complicated, but for the buyer it is actually very logical.

Section I helps you understand what kind of property this is.
Section I-Sp shows the rights related to ownership.
Section II answers the question of who has the right to sell the property.
Section III reveals risks, restrictions, and third-party rights.
Section IV shows the mortgage.
And wzmianka warns that the legal situation may be changing right now.
